Abstract

A paper support has an adhesive layer and a metallized holographic image, wherein the metallized holographic image includes at least two holograms, such that the first hologram is visible only by non-coherent light and the second hologram is visible only by coherent light. The holographic images are formed on a photosensitive element on a polymeric support by imaging steps, which include metallizing the holographic images and overcoating the holographic images with an adhesive layer. Next, the metallized holographic images are transferred to the paper by laminating the adhesive layer to the paper at a predetermined temperature and pressure, and subsequently delaminating the polymeric support from the paper, such that the holographic image remains on the polymer support for reuse.
